DMDMH Preservatives for Cosmetics&Personal Care

1. DMDMH Preservatives
2. Efficient broad-spectrum preservatives
3. Used in various cosmetics and personal care products

LT50 is a low cost but highly antibacterial preservative used in various cosmetics and personal care products. It is effective in inhibiting gram positive and gram negative bacteria, yeasts and molds. Because of its high efficiency at low concentrations, LT50 can coexist completely with cationic, anionic and non-ionic surfactants, emulsifiers and proteins. A series of experiments have proved that the LT50 has remained stable over a long time, a wide range of pH and temperature. Because it is very soluble in water, LT50 can be used in aqueous solution to facilitate production. Because it is colorless and tasteless, it can be used in a variety of formulations:
hair care Shampoo, conditioner, rinsing agent
Shave Coating liquid, paste, glue
Cosmetics Powder, bath powder, talcum powder
Liquid washing Bath lotion, lotion, skin lotion
Baby Care Shampoo, oil, powder
eye make-up Eye cream, eye shadow, eye liner
Sunscreen Net, oil, coating liquid
cream Antifreeze cream, moisturizing cream, hand / foot cream.
Daily chemical raw materials A mixture of surfactants, shampoos and hair care agents.

The main active ingredient of LT50 is the aqueous solution of dihydroxymethylhydantoin, which is an efficient and low-cost bactericide to ensure that the manufacturer can produce cosmetics and personal protective products at a relatively low cost. The cosmetics bath and Fragrance Association (CTFA) is named DMDM hydantoin.

Typical properties:
free formaldehyde,% Max. 1
Total formaldehyde,% 17.0
pH 7.0
Water, % 45.0
Appearance Clear liquid

Stability: The samples were stored at -18 ℃, 25 ℃ and 50 ℃ for one year, and the free and total formaldehyde content was detected. It is found that the product of LT50 has no change in composition.

Solubility: Soluble in any water phase. LT50 can also be added to cream, shampoo and face protecting water. It can be added at room temperature or at temperatures up to 80 ℃ for 6 hours without reducing the corrosion resistance. But mixing at high temperature should be carried out in a closed container, preferably in the cooling stage. LT50 can also be added to surfactants that need to be stored for a long time. Its temperature is usually between 50 and 60 ℃ and pH is between 7.5 and 8.5.

Cost: In today's competitive market, cost is the first consideration in the production of cosmetics and personal care products. Compared with other advanced preservatives, the cost of LT50 is lower. At the same time, LT50 consumption is small, but it is a highly effective broad-spectrum antibacterial agent. The cost of your antibacterial agent will be lower so that profits can be increased.

Technical services: The microbiology and technology laboratories of Tians have the capability of the above experimental projects. Microbiology and technology lab provide technical support and technical support to customers. If you need these customized technical services, please contact Tians sales center.

Safety data: There is sufficient information to show that the toxicology of LT50 is satisfactory, which ensures the safety of production and consumption throughout the process. LT50 has been extensively tested in toxicology and is equally safe Life Science Ingredients – Microbial Control and effective in both "resident" and "wash-out" products. Skin, eyes, ingestion and allergy studies show that LT50 is very safe on a clear surface and has the least toxicity at the recommended dosage.
